Just traveled 45 miles to a fish store today to get a new testing kit. And you wont travel over 6. I would ride my bike that far if I had to. I had a 55 one time that I stocked while I was working on my car. I rode my bike 10 miles each way to stock the fish after it cycled. I had them put on Oxigen and made sure I followed a smoth path. Oh yea this was a saltwater tank with very fragile fish. All survived the ride and the tank flurished for over a year at that location. I then moved the tank to my aunts 80 miles from there and they survived tell she poisened them off  :sad:. She didn't test test test like I told her 2.
